Description: Grid Couplings, is an advanced metal structure. It relies on the serpentine spring plate to transmit torque. Grid Couplings today's most advanced international mechanical drive shaft coupling components, is also a very common drive shaft coupling components. There are nine types of serpentine spring coupling type, namely JS radial-mount enclosure (Basic), JSB casing axially mounted, JSS double flange connection type, JSD single flange connection type, SJS pick middle shaft type, JSG high-speed type, JSZ brake wheel type, JSP with the brake disc type, JSA security type. Features and maintain Grid Couplings main structure consists of two semi-couplings, two and a half cover, two seals and serpentine springs slices. It is embedded in the spring by a snake cogging coupling halves to transfer torque to the serpentine spring coupling piece embedded in the two and a half couplings gullet to achieve link driving shaft and the driven shaft. When the operation is to rely on the active side face axial teeth snake spring force to drive the driven side to transfer torque, so in large part to avoid the resonance phenomenon, and the elasticity of variable spring when transmitting torque generated so that the mechanical vibration system can get better results than the average rate of 36% damping. 1, the axial coupling piece embedded in a serpentine spring for more than two and a half by 36%. Serpentine spring piece trapezoidal cross-section of high-quality spring steel, strict heat treatment, and special processing, with good mechanical properties, so that the coupling life than non-metallic elastic coupling element (such as elastic sleeve studs, nylon rod pin coupling) greatly increase. 2, the tooth surfaces of the two coupling halves are in contact with the arcuate spring, when the transmission torque is increased, the spring piece along the tooth arc deformation, so that the two coupling halves of the force acting on the point near the reed . The contact point spring with the tooth surfaces i.e. torque changes with the magnitude of torque transmitted varies, its transmission characteristics are variable stiffness. So that it has more than ordinary elastic coupling can withstand a greater amount of change in load. Reed along power transmission buffer when the tooth arc deformation generated, especially when the machine is started or strong impact load, there are complementary parts of security protection to a certain extent. 3, the transmission efficiency of the coupling by measuring up to 99.47%, and its short-term overload capacity is twice the rated torque, safe and reliable operation. 4, to protect the spring prevents aluminum casing thrown outwardly during operation, and the reservoir housing full of butter, not only good lubrication, and the noise is absorbed by the spring when engaged eliminate butter damping. 5, less machine parts, small size, light weight, and is designed to be a trapezoidal cross-section of the spring plate and the trapezoidal alveolar agreement is particularly convenient, compact, making assembly and disassembly, easy to maintain than the average coupling. 6, since the spring piece is a point contact with the curved surface of the tooth, so that the coupling can be obtained so that a greater flexibility. It can be installed in the same time there are circumstances under bias radial, angular and axial normal work. 1, vibration resistance, long service life. 2, withstand changes in the load range, starting safety. 3, high transmission efficiency, reliable operation. 4, low noise, good lubrication. 5, simple structure, easy assembly and disassembly. 6, the whole small parts, small size and light weight. 7, allows a greater misalignment. 1, for connecting two coaxial drive shaft system, high-power, has a two-axis compensation relative offset and shock absorption, cushioning properties, operating temperature of -30 ℃ ~ + 150 ℃, nominal torque transfer 45 ~ 800000N.m. 2, mainly used in lithotripsy machine, reciprocating crank, speed reducer, metallurgy, mining, lifting machinery. 3, shaft drive a variety of other machinery and equipment, and staff who have a motor connected to the motor and gear box linked to or associated with the shaft axis places can be applied. An installation careful alignment, control and reasonable deviation JSZ type brake wheel Grid Couplings allow greater misalignment though, but when installed, should be within the prescribed value of the gap between the coupling (1) two and the angular deviation of alignment, installation, every gap clovenfooted 凌斯 Grid Couplings between 90 ° measurement, the difference between the maximum and minimum values ??of not more than 0.38mm. (2) radial deviation find positive. With a ruler placed on two couplings, measured once every 90 °, with a foot race inspection, the radial deviation of not more than 0.38mm. 2 choose the appropriate grease oiling point temperature ≥150 ℃, can resist the centrifugal force, has a separate stability, no impurities, no corrosion of carbon steel and nitrile rubber lithium grease better. Run-for-3 to fill a sufficient amount of fat enough grease on Grid Couplings work is very important, it is recommended to check once a year. Injected with a dry oil grease gun until excess grease overflows in the hole.
